The GRACO G-Chem Beam Pump (SKU:. A23003) is a positive displacement plunger pump designed for chemical injection applications. It features a 1/4" Chromex coated plunger and HNBR (Hydrogenated Nitrile Butadiene Rubber) seals, ensuring robust performance and chemical resistance. This pump is intended for reliable, low-maintenance chemical dosing in industrial and oilfield environments.

Key Features:

• Positive displacement plunger pump
• G-Chem Beam Pump, 1/4" plunger
• Chromex coated plunger, HNBR seals, stainless steel wetted parts (unless otherwise noted)
• Varies by model; for similar 1/4" simplex models, up to 2500 psi (17.2 MPa, 172 bar) possible (confirm with specific model documentation)
• Designed for chemical injection systems, compatible with various chemicals depending on seal material
• Easy access to plunger and packings for maintenance
• Plunger packings can be replaced in 10 minutes or less
• Robust and simple design with adjustable fluid packing
• Proprietary poppet style check valve to prevent sticking
• Same high-quality drive train as other GRACO chemical injection pumps

Applications:
Chemical injection for oilfield, industrial, and agricultural applications; suitable for use with pumpjacks and other automated systems

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems
• Follow manufacturer’s instructions for mounting and plumbing
• Ensure proper alignment and secure mounting to prevent vibration and leaks
• Use compatible chemical hoses and fittings rated for the intended pressure and chemical
• Regularly inspect and maintain seals and packings for optimal performance
• Replace plunger packings as needed (typically every 6–12 months or as per operating conditions)
• Check for leaks and wear during routine maintenance
• Keep pump and surrounding area clean to prevent contamination
